We are lucky enough to have a garden which has a small stream running through it. This never gets more than 1 - 2inches deep and is continually flowing.
It is bordered by 8ft high banks which have been planted in the past with various shrubs heathers ferns, but in places creeping buttercup and ground elder try to rule. We do not really have any water edging plants down there and I would really like some. This year in spring I split some hostas and put those there and they have done really well about 1 foot away from the water. I intend to split more hostas in the autumn as they are getting ratehr large in the rest of the garden and free plants are the best!
Could I get some recommendations for other edging plants that will beat the buttercup and ground elder though I do my best to dig these out. the ground elder not so much a problem near the water but the buttercup loves it. We are also on a tight budget so nothing too expensive!
The stream is only a foot wide, so nothing too tall either. We live in Scottish borders and it is COLD here in the winter, though this is a wooded area and so does not get frost too much.
